Hello!

I've decided that I don't really need a 2.5" lift and see where OME springs are 1.5" & 1.75" which is ok for me. I'm going to use 245/70-16 tires and do some beach driving but mainly it's a daily driver and the lift is just for looks and maybe light trails someday.

What's the difference between the medium and heavy duty springs? Which one is better for the ride and will the lift height be the same for both? Should I use HD in front and medium in the rear or HD all round?

I already have OME shocks and struts as I was going to put a 2.5" lift on but plan to use them with the 1.5" lift instead.

Thanks!

If you pull atrailer some or load the back heavy I would go with the HDs in the rear if not the mediums will or should be OK as far as the front I like my Heavy Dutys, before I installed the ARB I ran them about 2500 miles or so and rode great, now around town with a bunch of potholes its a little rough, but out on the road feels great. Around town is not bad, but some people like a mushy suspension

Do you know the rear HD part number off the top of your head? Since adding the RL rear bumper, I think I might need to add a heavier rear coil. I am afraid what the butt end is going to do once loaded up for the Moab trip.

we have had the med.'s on the wifes Kj for over 5K miles and love the ride
10X better than stock
I have no problem with 2 people + stuff on the rear so I dont see where the HD's on a DD with factory rear bumper and tire carrier would be needed
the same for the front we have no "chop" even on the great streets of New Orleans

1 thing to keep in mind when using OME stuff ,from what I read, they tend to "build" their stuff based on what they say
that is if they say that it is for "all stock" then it is just that IE light duty
I would no mix light and med or HD and med springs
The rate of the springs is based on them maching so with HD's in the rear and med in the front when you hit a bump the front will be nice and smoth and the rear will be like ridding on a pcs farm equipment unless it has a preload on it but if you are not carring 200# of "stuff" in the rear hold on

Thanks Jason! That's exactly the information I was looking for. I'm going to go with the mediums front and rear. I don't want a stiff ride where I feel every little bump in the road and I do notice quite a bit with my stock setup.

With the Mediums how did the lift turn out. Is there much of a Rake in the front end so that it sits a lot lower than the back?

No chop out on the road at all with the Heavy Dutys!!!I have been from Ohio to FLA. twice and Ohio to Boston 5 times now plus all the other trips and I would never ever run anything but the Heavy Dutys. Just returned from a "weekend" trip of over 650 miles and on the interstate is just floats along very smooth! And you are right about OME building their stuff right, designed for the vehicle not designed to fit whatever.

at first I had 2" then I got right at 1.75" over stock after 2500 miles and been that way
I had some real bad spring sag after 38K

Not much rake at all if I wanted 0" I could do a clevis lift and be fine but for now I am leaving it alone
when it comes time for new tires ,in 3 months, I may do it then but it will depend on the price of 245/70's vs 245/75's

Not sure how much it lifted but I know that with 2.5 inch spacers under the stock springs I now sit level front to back, of course it had a front rake to it before so I know I gained 2.5 at least (with the clevis). Plus thats with the ARB hanging on there, has not really dropped any at all maybe 1/8 of an inch??? and over 20,000 miles now
I have been experimenting with OME Heavy Duty rears/ stock springs with 2.5 spacers and another off brand spring as far as flex goes, just playing around on those cold nights .

what????

I am not sure that i follow but let me try
you got OME HD's up front with a clevis and an ARB bumper and netted ~2.5"
and in the rear you got OE springs with a spacer and netted 2.5" the same with the OME HD's?

If so then that would be close to the same as with the mine if I did a clevis today
when I had a bad rake from spring sag I did a clevis and gained 3/4" at the front most part of the unibody behind the front tire
add that to the 1.75 after settling and thats 2.5" I do know that if I add the ARB bumper it will go down an easy 1/4"

The big problem that I will have with doing the clevis lift is that the front will be >1/2" higher than the rear and I think that I will notice it to much

When I have the OMEs in the rear I also have some extra stock spring spacers or whatever you call them, minds blank today, blond moment ya know. BUT right now I have the stock rear springs in with the stock upper and lower rubbers and a 2.5 inch (daystar ? I think) spacer and it sits level with the ARB on. When I bought my used ARB I got some extra suspension parts so I have been playing around with different combinations of springs etc in the rear.

I have the HD's front and rear, along with everything listed in my sig. After installing my lift the ride improved greatly over stock. Not to stiff at all. Now after I added the BFG KO's, things got a lot stiffer, but that was a result of going from mush sidewalls to steel sidewalls. I have no aftermarket bumpers and only the Mopar skids, and I'd get the HD's again without question. I got 2.5" of lift in the rear with the OME HD's.

That sounds good to me I don't mind a slight rake and I don't want a harsher ride so the OME mediums would prob be perfect for me. I'll prob get them when I have some more mileage on my KJ and need new shocks anyway. That way I can rationalize replacing shocks and coils.

That is the main reason that I changed the coils
I needed shocks and struts so for $200 more I got the OME springs and some lift it was a no brainer
there was no extra charge for having the new coils installed due to the fact that the old ones needed to be removed in order to install the new struts
